Serial No. 615,604.

To all whom it may concern:

Be it known that I, ARTHUR A. GERMAN, a citizen of the United States,and a resident of Duluth, in the county of St. Louis and State ofMinnesota, have invented a new and Improved Gun-Sight, of which thefollowing is a full, clear, and exact description.

Among the principal objects which the present invention has in view are:to provide an attachment for the peep sight of a gun adapted for rapidand easy adjustment for changing the size of the opening and to providea construction for an attachment of the character named which is simpleand durable.

One embodiment of the present invention is disclosed in thestructure'illustrated in the accompanying drawings, in which likecharacters of reference denote corresponding parts in all the views, andin which- Figure 1 is a perspective view of a fragment of the stock of arifle having mounted thereon a peep sight provided with an attachmentconstructed and arranged in accordance with the present invention; Fig.2 is a vertical longitudinal section of a peep sight having anattachment constructed and arranged in accordance with the presentinvention; Fig. 3 is a detail view showing the movable standard andtarget of a peep sight constructed in the usual manner and havingmounted thereon a graduated sight opening plate constructed and arrangedas per the present invention; Fig. 4 is a detail view, in perspective,of the pivoted standard of a peep sight; and Fig. 5 is a cross sectiontaken on the line 55 in Fig. 2.

As shown in the accompanying drawings, the pivoted standard isconstructed in the manner usual with gun sights of this character havingthe split sections 11, 11, the core pitch screw threaded section 12, andthe hinge disk 13. The disk 13 as is usual in sights of this characteris held between the ears 14, 14 set up from the base of the plate 15.Through the ears and hinge disk is extended a pivot shaft 16 about whichis closely wound the spring for raising the standard to the verticalposition.

Slidably mounted within the standard 10 is a movable standard 17. Thestandard 17 has provided on the sides thereof rack tooth sections 18,18. The sections 18, 18 extend between the split sections 11, 11, thesame forming guides for the travel of the said standard 17. Mountedrigidly on the upper end of the standard 17 is a cupped target disk 19.The target disk 19 is provided with an annular flange 20 through aslotted perforation in the side whereof is extended a stop plate 21.

The plate 21 is constructed in accordance with the present invention andis pivotally mounted by means of the pivot pin 22 upon the target disk19. The plate 21 is provided with a series of graduated perforations 23,24, 25, 26, 27, 28. The perforations 23 to 28 inclusive are graduallyenlarged from a point opening to an opening as large as the peepopenings 29 and 30 formed in the center of the target disks 19 and 31respectively.

The plate 21 is provided with a series of peripheral recesses 32, 32adapted to receive the bent end 33 of the spring 34. The spring 34 isdesigned to hold the plate 21 in fixed position when either of theperforations 23 to 28 inclusive is concentric with the openings 29 and30 and to center the said perforations with the said openings. Thespring 34 is extended through a slot formed in the flange 20 as shownbest in Fig. 3 of the drawings. It is held in the slot by the disk 31which is provided with a flange 35 to extend over and enfold the flange20 of the disk 19, forming thereby a hollow casing in which the majorportion of the plate 21 is contained. The peep sight thus constructed israised and lowered by means of a knurled sleeve 36. The sleeve 36 isinternally threaded to register with the teeth on the sections 18. Thesleeve 36 is held in position by the beading 37 formed at the upper endof each section 11 of the standard 10 and by the lock nut 38 which isinternally threaded to register with and be engaged by the threadedsection 12 formed on the sections 11, as shown best in Fig. 2 of thedrawings.

When in operation the nut 38 is manipulated to release the sleeve 36.The said sleeve may be manipulated to raise and lower the standard 17,the section 18 being tooth engaged with the threads on each side of thesleeve. When the target formed by the disks 19 and 31 and the plate 21has been elevated or disposed to accommodate the conditions under whichthe sight is being used, the nut 38 is manipulated to engage the sleeve86 to clamp the same into fixed position, thereby holding rigidly andfixedly the target.

With a gun sight so constructed, the operation is as follows: The heightof the center of the target having been fixed by manipulating the sleeve36 and nut 38, the gunner, by engaging the edge of the plate 21 extendedbeyond the flange 20 as shown best in Fig. 3, moves the plate to presentany one of the graduated perforations 23 to 28 inclusive in line withthe openings 29 and 30 and concentric with the target formed by thedisks 19 and 31. The condition of the prevailing light dictates the useof the particular perforation which shall be used. The distance at whichthe mark is removed also influences and controls the use of theparticular perforation adjusted. By means of stopping down the size ofthe opening through which the forward sight is viewed, a finer andcloser adjustment of the sight mark is permitted, this being necessaryand possible in accordance with the distance of the mark and thecondition of light.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is A gun sight comprising a target providedwith double walls to form a box-like structure, said walls having each asight.

opening in the center thereof; a stop plate pivotally mounted betweenthe walls of said target to extend beyond the edge thereof, said stopplate being provided with a series of size graduated perforationsadapted to register with the center of said sight openings, said stopplate being provided with a series of rounded recesses formed in theperiphery thereof; and a spring mounted between the walls of said targethaving a head adapted to bear against the opposite walls of saidrecesses to move the said plate to register the said perforations withsaid sight openings said head being arranged to ride out of saidrecesses in both directions.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
